Narrative Opinion Summary
In this case, the estate of the deceased plaintiff filed a wrongful death lawsuit against Navistar International Transportation Corporation, alleging negligence in the design, manufacture, and sale of the Farmall 450 tractor, which was involved in a fatal accident. The tractor, manufactured in 1957, had a seat mounting design flaw that allegedly caused the deceased to be ejected and fatally injured by an attached rotary mower. The trial court ruled in favor of Navistar, dismissing claims regarding post-sale warnings and retrofitting. On appeal, the court found multiple procedural errors, including the jury's unauthorized experimentation with a tractor seat assembly not admitted into evidence, and the admission of speculative expert testimony from Navistar's expert. The appellate court reversed the trial court's judgment, citing manifest prejudice due to the jury's exposure to new evidence and unreliable expert opinions, and remanded the case for a new trial. The court also upheld the dismissal of negligence claims concerning post-sale warnings and retrofitting, aligning with Illinois precedent that does not impose such duties absent statutory requirements or voluntary actions by the manufacturer.
Legal Issues Addressed
Admissibility of Expert Testimonysubscribe to see similar legal issues
Application: The trial court's decision to admit Navistar's expert testimony was contested due to its speculative nature, which the appellate court found to be inadmissible.
Reasoning: Expert opinions must have a sound basis; if they rely on uncertain factors requiring speculation, they are deemed unreliable and inadmissible.
Duty to Provide Post-Sale Warningssubscribe to see similar legal issues
Application: The court examined whether Navistar had a duty to provide warnings about defects discovered after sale, ultimately affirming dismissal of post-sale duty claims due to lack of duty absent statutory requirements.
Reasoning: If the post-sale warning claims referred to dangers only recognized after the product left Navistar’s control, the manufacturer had no duty to warn.
Jury Deliberations and New Evidencesubscribe to see similar legal issues
Application: The court determined that introducing new evidence during jury deliberations, such as the seat assembly, was prejudicial, warranting a new trial.
Reasoning: The experiment lacked procedural safeguards and effectively introduced new evidence, resulting in manifest prejudice.

Application: The appellate court found that allowing the jury to examine and experiment with the tractor seat assembly not admitted into evidence led to manifest prejudice.
Reasoning: The court agrees with the plaintiff that the jury’s access to the seat assembly was inappropriate, as it was not introduced into evidence and invited unauthorized experimentation.
